FAUCET.

Specification of Letters Patent.

Patented May 1.9, 1:914.

Application filed January 10, 1913. Serial No. 741,266.

To all where 2'25 may concern Be it known that l, COURTLAND W. lVnAvnn,a subject of the King of Great Britain, residing at Toronto, in theProvince of Ontario and Dominion of Canada, have invented new and usefulImprowements in Faucets, of which the following is a specification.

The invent-ion relates to faucets and has for an object to provide aquick opening and closing faucet.

The invention embodies, among other features, a faucet in which but aslight movement of the handle moves the valve into open or closedposition, and in which the stroke of movement of the valve with respectto the valve seat of the casing of the faucet can be increased ordecreased to con trol the flow of fluid through the casing of thefaucet, thus increasing or decreasing the swing of the handle inactuating the valve.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification. inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a vertical sectional view of the faucet; l ig. 2 is a sideelevation of the valve and operating mechanism therefor, removed fromthe casing of the faucet; Fig. 3 is a perspective view, looking at thecam portion of the adjusting member; and Fig. 1 is a horizontalsectional view taken on the line 4-4: in Fig. 1.

Referring more particularly to the views, I employ a faucet comprisingthe usual faucet casing 11 having an inlet end 12 and an outlet end 13,a valve seat 14 being formed in the casing 11 between the inlet andoutlet 12 and 13, as shown.

A valve operating mechanism 15 includes a stem 16 terminating at thelower end thereof in a head 17 having a quiclethread 18, the lower endof the said head 17 form ing a valve 19 by mounting a washer 20 on thelower end of the head, the said washer being secured thereto by a screw21 passing longitudinally in the head as shown, it being understood thatany convenient form of valve 19 can be provided at the lower end of thehead, the said valve bein normally adapted to repose on the valve seat 11 in the casing 11. The threaded portion of the head has threadedconnection with a tubular portion 22 of the casing 11 and by providingthe quick-thread 18 it will be readily seen that only a slight rotationof the stem 16 is necessary in order to seat or unseat the valve 19.

ran adjusting member 23 is mounted to slide on the stem 16 and comprisesa collar 241 having an integral nut 25 with a depending cam member 26formed with the collar 24-, a suitable packing 27 being arranged toencircle the same within the cam member and secured therein by a locknut 28 also lying within the cam member 26, the said collar 24 beingfurther provided with a washer encircling the cam member at the innerend thereof and at the point of formation of the cam member with thecollar.

Nov: when the head 17 has been threaded in the tubular portion 22 of thecasing 11, a retaining nut 80 is threaded on the upper end of thetubular portion of the casing and is provided with a flange 31 engagingthe collar 21 to retain the adjusting member 23 in position on thecasing. The upper end of the stem 16 is tapered and provided with aseries of longitudinal serrations 38, the said upper end of the stembeing adapted to be received in a tapered opening 3 1 formed in a handle35, the wall of the said op ring 34 being provided with a series ofvertical notches 3G in which the serrations 33 of the stem are received,thus locking the handle 35 on the stem and preventing rotation of thehandle without rotating the stem a screw 37 being preferably threadedinto the stem from the upper end thereof, with the head of the screwengaging the handle, thus securely locking the handle on the stem.

Now referring to Fig. 1 it will be seen that when the faucet isassembled, the nut 25 of the adjusting member 23 will project outwardlybeyond the retaining nut so that a wrench can be readily applied to thenut 25 for the purpose of actuating the adjusting member 23, and it willbe further seen that when the handle is actuated to open the valve 19with respect to the valve seat 1-1, the upper end of the threaded head17 will engage the cam member 26 of the adjusting member 23, thuslimiting the upward movement of tl e head and consequently also limitingthe throw of the handle 35. It will be apparent that only a slight turnof the handle is necessary to move the valve into open or closedposition, this being due to the provision of the quick-thread 18 on thehead 17. If, however, it is desired to not only reduce the throw of thehandle but also shorten the vertical movement of the valve with respectto the valve seat, thus restricting the fiow of fluid through the casing11, the application of a wrench or other implement to the nut 25 willresult in the rotation of the adjusting member 23. Now referring to theviews, it will be apparent that the upper face of the head 17 isinclined to conform to the inclination of the lower edge of the cammember so that, normally, the cam member will seat smoothly and evenlyupon the upper face of the head, it being thus seen that the length ofthe head 17 varies on account of the inclination of the upper facethereof. A slight adjustment of the adjusting member 23 will adjust thestroke of the valve to various distances between the shortest andgreatest stroke thereof, it being understood that the adjustment of thethrow of the valve is accomplished without removing any of the parts ofthe faucet.

Having thus described my invention, 1 claim:

1. in a faucet, the combination with a casing, of a valve seat formedtherein, a stem depending in the casing, a head carried by the stem andhaving threaded connection with the casing, the said head having aquick-thread thereon, a valve formed at the lower end of the said headand Copies of this patent may be obtained for adapted to normally seaton the said valve seat, with the upper face of the said head inclined, ahandle for the stem, and an eX- teriorly adjustable cam-like memberloose on the stem and revoluble on the casing, the said member beingadapted to engage the inclined face of the said head for adjusting therange of vertical movement of the said stem relatively to the saidcasing.

2. In a faucet, the combination with a casing, of a stem revolubletherein, a valve carried by the stem, and adapted to engage the valveseat in the casing, a head on the valve having its upper face inclined,and eXteriorly adjustable means revoluble on the casing and looselyencircling the said stem for engagement with the inclined face of thehead for adjusting the range of verti cal movement of the valverelatively to the said valve seat.

3. In a faucet, the combination with a casing, of a stem revolubletherein, a valve carried by the stem and adapted to engage the valveseat in the casing, a head on the valve having its upper face inclined,and an eXteriorly adjustable cam-like member on the said casing andadapted for engagement with the inclined face of the said head foradjusting the range of vertical movement of the valve relatively to thesaid valve seat.

In testimony whereof I aflix my signature in presence of two witnesses.
